TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 499,432, dated June 13, l893.

Application filed December 29, 1891. Serial No. 416,450. (No model.)

To all whom it may concern.-

Be it known that LWILLIAM LUMLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in temporary binders for holding letter file indexes conveniently for the ready insertion of letters, bills and'other documents during the continuous use of the file, and before the permanent storage of such matter.

The present invention is more especially designed as an improvement on a device of this character covered by United States Letters Patent No. 532,537, granted to me July 22,1890.

One of the objects of my invention is to improve and greatly simplify the means for holding the impaling pin or bar which passes through the perforated tabs of the index sheets, securely in place, but with capability of being readily and quickly removed and replaced without the necessity for manipulating any screws or slides or the like.

Another object of the invention is to provide a temporary binder with a simple and efiective file holder for holding the papers and index sheets down smooth and flat in the box or drawer, which shall consist of a minimum number of parts and be so constructed as to spring toward or from the papers after passing a certain point.

With these ends in view my invention consists in certain features of novelty hereinafter more fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a general perspective view of a file drawer or box provided with my improvements. Fig. 2, is a detail vertical sectional view taken on the line 2, 2, Fig. 1, on a larger scale. Fig. 3, is a detail View showing the means for securing the impaling pin in position. Fig. 4:, is met:- tional plan view taken on the line 4, 4, Fig. 1. Figs. 5 and 6 are perspective views of modified forms of impaling pin hereinafter more fully described.

In the drawings wherein like signs of reference refer to like parts throughout the several views, A, is the box or drawer, and B, are the index sheets arranged therein and having the perforated holding tabs 0, all of the usual or any suitable and convenient form.

In carrying out the preferred form of my invention, I provide the front of the drawer or box in its inner side with a vertical or uprightchannel or groove D, of sufficient width and lateral depth to receive the attaching tabs (3. This groove extends preferably from within a short distance of the top or upper edge of the drawer to a point slightly below the surface of the bottom of the drawer so as to form a socket E, in said bottom. The groove D, may be of any desired contour and formed by any of the well known methods, as for instance by gouging, routing or boring, but preferably by boring, and as incidental to this preferred manner of making the groove or channel, it will of course be of semi-cylindrical contour, while the socket E, will be circular in form.

F, is the impaling pin or rod which passes through the perforated tabs 0, and thus holds the index sheets squarely in the box or drawer. This pin F, is preferably formed of a single piece of wire or spring metal having near its upper end a thumb knob or handle G, formed by taking a turn or coil in the wire, which coil is preferably elliptical or flat so as to be as little as possible in the way of the documents and index sheets when they are folded backward in the ordinary manner. Just above this thumb piece G, the wire terminates in a tenon H, which fits in a complementary socket or cavity 71., preferably formed in the portion of the drawer front just above the end of the bore or channel D, thus holding the upper end of the impaling pin in position.

When it is desired to slip the index sheets upon or remove them from the impaling pin, the tenon H, may be inserted through their perforated tabs 0, and the pin then turned through the hole after the manner of an ordifer, however, to employ as an effective and inexpensive arrangement, a spring formed integrally with the pin itself, thus at the same time providing the pin with a stop or button for preventing the tabs from slipping off at the lower end of the pin. This preferred form of spring is made by simply taking a spiral turn or coil I, in the lower end of the wire of which the pin is formed, which coil also constitutes a foot which fitsin the socket If, and is preferably of the same, or substantlally the same diameter as said socket, so that the pin will be held firmly against laterall displacement or movement at its lower en When it is desired to remove the index sheets from the impaling pin forany purpose, a slight downward pressure is applied to the thumb piece G, so as to disengage the tenon H, from its socket, whereupon the pin may be drawn outward and lifted from the socket E. The coil G, not only serves as a handle or knob with which to manipulate the pin, but constitutes a top stop for preventing the tabs from slipping off at the top of the pin when the end of the latter is out of its socket h. As a modification of this arrangement, the spring and foot at the lower end of the impaling pin may be formed separately of a bow or blade spring I secured to the end of the pin in any suitable way as shown in Fig. 5. In this instance, however, the socket for the reception of the spring foot will be formed by cutting transverse sockets E, on both sides of the bore D,below the surface of the bottom of the drawer. And as a modification of this blade spring, the end of the Wire of which the impaling pin is formed, may be bent at an angle so as to form a spring piece 1 and a foot rest 1 and if desired such bent portion flattened as shown in Fig. 6.

K, is the holder which I have herein termed a file holder, for holding or compressing the papers and index sheets in the drawer so as to prevent their free edges from curling up and interfering with the drawer being pushed into the usual cabinet. This holder consists preferably of a single piece of wire or other strip bent into a suitable form best adapted for bearing upon the papers, whose arms 7c, are each provided near their extremities with a portion bent at an angle thereto, and forming journals 7t journaled in loops L, secured on the inner side of the front of the drawer by means of screws M, entering shoulders formed on the front portion of the drawer,- the said portion of the drawer being cutaway as shown and the journals let in flush with the surface thereof. The said journals 7c,

terminate in short cranks or cams K which project outwardly and are provided with beveled or rounded ends which are adapted to impinge against theinner side of astoutblade spring N, respectively near the ends of the latter, and thus cause the holder to spring up or down according as the points of contact between the spring N, and the cranks K are above or below the center of bearing of the ends of said cranks. Thus if the holder is pushed down until the spring bears on the upper sides or bevels of the cranks, the pressure of the spring will continue such downward movement; and on the other hand, if the holder is elevated until the lower sides of the cranks begin to receive pressure from the spring, the holder will be thrown into a vertical position, and there held. This spring N, is preferably formed in one piece and let in flush with the end of the drawer to which it is secured by means of screws 0. But obviously such spring mightbe formed in two pieces if desired, without departing from the spirit of my invention.

A temporary binder thus constructed is simple and durable, and consists of but a minimum number of parts with no frail or complicated mechanism liable to break or become deranged, or to interfere with the free use of the device.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
